To all whom it may concimi.-

y Be it known that I, FRANK WHITNEY, a citizen of the, United States;residingat Hubbard Woods, in the county of Cook and State of Illinois,

y present invention relates to im rovements,in roller bearings, and ithas or its object primarily toi" rovidean improved liearingwhichrembodies pairs of cone sui-- faces, the cone 'surfaces-.of f eachpair being Qf the same angle, andthe cone surfaces of' one pair beingarranged at the saine angle but inclined inan oppositedirection wit-lirespect to the cone surfaces of 'another pair, in combination with. setsof roller elements, one set of roller eli'iientscoperating with eachpair ofcoi'i'e surfaces, and `each roller element bein of a compositestructure, that is to say,- 1t is built lup of a plurality of axiallyalined rollers having each roller element being cylindrical in form soas to y.obtain an even bearing upon the opposed cone surfaces, and thecomposite formation of the roller ,elements enabling them to roll uponthe cone surfaces without breaking or undue friction notwithstanding thedifferential paths over Awhich the rollers ot the roller elementstravel.

Another object of the invention is to;pro

vide a roller bearing which when once iidautomatically maintainj ustedis capable of ing such adjustment, and also a bearing wherein the innerand outer cones and the 3 roller engaging surfaces thereof are capable'of adjustingr themselves .accurately to the size and shape of the shaftoi' journal and the journal box or pense of grinding is obviated,the'adjustable outer cone surface and the inner cone surface beingprefei'ablyprovided with hardened linings which are not only capable ofautomatically accommodating themselves to the conesurfaces and to thecoperating roller elements,biitxsuch linings when formed of resilientmaterial have a tendencyo contract andexpand respectivelythereby bindingthe inner concor cones upon the shaft or journal, and tlie'onter cone orcones withinfthe box Vor casing, driving fits between Ethese parts beingtherefore unnecessary.

Further objects of the invention are to f'havelainvented new and* usefulImprovements-in RollerfBearings, ot which the following-is nspecification.

a detail view of a casing, whereby the e'xrelation Fig. 11

provide devices torv automatically maintaining a proper rollingengagement between the ro ler elements and thecoiie surfaces whereby theload or pressure shall be distributed evenly between all ofthe rollerelements,

:thus avoiding breakave of the parts, and to maintain a proper ajustrnent of thebearing andthereby take up any radial or thrust motionthatwould otherwise occur owing to wear orother causes.

To these and other ends, the invention consists incertain improvements,and com. hina :ns and arrangements of parts, all as will nehereinaftermore fully.V described, the 4novel featuresbeing pointed outparticularly 1n the claims at the end of the specification'.

Roller bearingsconstructed in accordance with my present invention arecapable of use generally in all cases where it is desirable or,necessary to eliminate or minimize friction. Owing to the variousconditions in which thebearing may be used in practice, it is obviousthat the construction of the bearing itself and the construction andarrangement of the inner and outer cone surfaces may differ in orderthat-the best re# sults may be obtained. In the present instance,l haveshown-several embodiments of the invention, but in each case,the mainprinciples of the invention are involved.

In Figs. l to 9 inclusive, I have shown an anti-friction bearing whichis adapted to sustain relatively heavy loads and one which is capable ofsustainingradial and also. end

l thrusts in both directions. In this instance,

1 designates the shaft and 2 designates the housing or easing, the shaftand housing belng as usual relatively rotatable. A pair of inner cones 3and et are applied to the shaft and they may be s'plined upon the shaftso that while there can be no relative rotation between these innercones and the shaft, the inner cones are capable of a relative axialmovement. To enable the bearing to be applied to a crank shaft, eachinner cone may be divided or split in sections as shown, and

these sections may be maintained in proper relation by dowel pins, asshown, or by any other suitable means.

One of the subsidiary features of my invention involves the provision ofmeans for automatically maintaining a correctadjustment of the bearingto compensate for wear and other conditions. For this purpose, ancxpansible Washer 5 is 'shown in Fig. l as interposed between the inneror adj acentends ofthe cones. These inner cones are so placed upon theshaft that their bases are opposed to one another, and theircircumferential faces are of the same angle. To facilitate and cheapenthe cost of manufact-ure of the bearing, I p refer to provide the innercones with hard metal linings or bushings which are capable ofaccommodating. themselves automatically to the respective cones and ofproviding true rolling surfaces for the roller elements. Inthe presentinstance, each lining or bushing 6 1s composed of .a spirally woundstrip of hard metal, t-he lining or bushing so formed being sprung intoa circumferential retaining groove or recess 7 in the respective lnnercone. In some cases, it may be necessary to interposea soft metalbacking 8 between the hard'metal lining or bushing and the cone. Theresilience of the lining or bushing 6 serves to bind its respcctive coneupon the shaft or journal.

The caslng 2 contains a pair of`outer cones Q'andl() the surfaces ofwhich are precisely parallel with the rollerv engaging surfacespresented by the inner cones 3 and 4. In

other words, the pairs of cones 3 and 9 and 4 and 10 are of equalangles. The inner or adjacent ends of theouter 'cones 9 and 10 which aretoward 'theapices of these outer cones are preferably separatedinitially a distance sufficient to allow for suitable adjust-ment, theouter cones 9 and 10 being capable of relative axial Vmovement Within,the housing or casing2 for this purpose. One end of the housing 2 maybe permanently closed. 'lhe other end,however, is preferably providedwith4 a removable and adjustable Wall 11 which in the present instanceis threaded into the housinir and is provided with'an annular series ofnotches 12 to receive a dog -thel pairs of cones and the rollerelemental prefer to employ a pair of expansible washers 15 and 16 whichare interposed between thebases or outer sides of the con's 9 and 10 andthe'respective walls lof the housing, each outer cone being capable offollowing the corresponding inner cone while the bearing adjusts itselThe roller elements according to my present invention are each com osedof a pl11- rality of axially. alinedre atively narrow rollersor diskswhich are of equal diameter or, in other words, each roller element iscylindrieal and adapted to bear evenly upon the parallel surfacespresented by the respective pair of inner and outer cones'. In

the present instance, each `roller element is composed of a plurality ofrollers or disks 17, each roller or disk havinga face which is less inwidth than` the diameter of the,ro1ler, and the -rollers of eachcomposite roller element are maintained in axial alinement by a cage ofsuitable form. These rollers may be substantially rigid, but I generallyprefer to use rollers which are sufficiently hollow to render themyieldable radially to adegree that will enable them to overcome anydiametrical distortion due to the hardening ztreatment to which they'are preferably subjected. The marginal edges of each roller, accordingto my present invention, are preferably chamfered as at 17, so thatwhile in :the assembled bearing, the. roller of each composite rollerelement has a line contact with the cone surfaces, the length of thecontact is such as will reduce friction to a minimum during thedifferential rolling Aaction of each roller element, and moreover, thereare no burs or relatively sharp edges to wear of the rollers and causetroublein the bearging. TherollersV or sect-ions ofeach roller,''lem'ent may be ofy different. numbers or widths as shown in-Fig. 1,in order that they will be oiset'relati'vely in their travel around 4theconical surfaces;

in 3 and 4, I have shown a cage y Agiihicli is composed of a pair ofinner and ,'Jiitcr rings 18 and 19, these rings being con- "lllfnectcd'at suitable vintervals by transverse "pins 20, and theetransverse connecting pins v .aetween the rings of each cage formjourpals or pintles on `which the rollers 17 of 'irtiposite rollerelement are freely y iirnablef' The'rings 18 and 19 of the cageare-preferably 'dished as shown in order that tlicy'niay compact-lyreceive andl con- Vtain the roller elements between them. In Fig. 8,however, I have shown a form 'ot' cage whereinit is unnecessary toprovide a pintle-orjournal for the rollers .of each roller 'x'zlenient,Afit-'set of spacing' blocks 2l lbeingirigidlynnited with the rings ofthe :cage this form and have concave opposed -il'fiaccs 22l whichconform to and cooperate' "'-with the peripheral surfaces of the rollers23 which in this forni may be iniperforate.

In orderto guide each cage laterally and to, retain the cage and rollerelements upon each inner cone after removal from the bearing, Ipreferably employ a pair of retaining rings 19npcn 'each inner cone.

It'visgenerally Vpreferable to so construct the outer cones S) and thatthey may expand and thereby adhere and adapt them selves perfectly totli'e box or housing, thereby avoiding the necessity of grinding thecones and driving them into the box. In Fig'. 9, 4I have shown in detailone of these outer cones which is split at :'34 ou a diag: onal lineso'as` to avoid an abrupt interrption in the'cone, and in this instance,the inner circumference of the cone is recessed at 25 and contains aresilient and expansible lining or bushing 26 which is fornied of a'coiled length of hard metal similar to the bushing or liningt for -theinner cone, the eiqiansivetendency oi this lining or bushing 26cansingthe cone S) or 1() to expand with- 5 0 in and adhere firmly to theinterior of the 'box'. The ends of the lining are sc formed `sto avoidan abruptl joint for the roller 'leinents.

' The bearing shown in Figs. 1 to 9 inlusive is, as previously stated,adapted for 'is'e intliose cases where the shaft must sustain aconsiderable radial pressure' and is also subject .to end thrust` in oneor both directions. In practice, the adjustable Wall.

11 of the housing, after the elements ofthe bearing have been introducedin to the hous` ing, is adjusted so that the cylindrical roller``"elements will revolve freely between 4the parallel and. oppositelydisposed pairs of B6. 'conc surfaces, care being exercised tha-tthere.

is no lost inotion in the bearing. "After the bearing has been appliedto the shaft, the expansible washers will act. to automatically maintainthe adjustment, thereby conipensating for -wear and also insuringevendistribntlon of the load ltween all ofl the -roller elements.ObvionslI inap l ing the bearing to crank shafts and the lille, the in#ner cones of the bearing must he divided or split in halves, ashereinbefore described, whereas in other instances, it will be'unnecessary to split or divide the inner cones.'

In Figs. `10 to 1l inclusive, l have shown two forms of bearings whereinthe twosetsof cylindrical roller elements are arranged in tandemrelation, that is to say, they are placed in the saine plane, and such aconstruction is very desirable, if not necessaiy.L in some cases where4only a short length'of the shaft is available forthe bearing.- ,lu Fig.10, a member 27 is fixed to the shaft- 28 and is formed willi a pairofreversely, disposed conc surfacesZS) and 30 which diverge at equalangles.4 The casing 31 is provided with an outer cone surface 32 whichis parallel to the inner cone surface 29, and the outer casing or4housing is, also provided with a. removable and ad`X justable sect-ionllwhich is formed with an outer cone surface parallel to the inner conesurface 30.' For convenience, the detachable and adjustable section 33of theihonsing may be threaded vinto vthe-body of the housing and it maybe secured or held in proper adjusted position 100 by a retaining devicesuch as shown 1n F igs;

l and 2. The parts of the housing may also be provided with internalangesan'd which overlap the 4member 27,' ,and felt wnsllcl'h' 38 1nd 39muy be Withinthe .105. flanges and'thereby serve asfdnst-exclndingmeans. In this form ofltheinvntion, two. sets ofcomposite'cylindricalfroller elements are employed as in the precedinginstance.` These two sets of roller elements, in this form are alsoguided and contnix'edwithin a single cage 40.l For. convenience, thecage may be formed in halves divided diametrically, the' halves beingduplicates. Each half of the cage-in this form of ;the invitan-'115.

tion is tubular having a substantially rectangular cross-section,'-thcends ofthe, cage' sections being' preferably broughtfltpg'ether andlapped and then secured bysuitable. screws 41. This cage ,is vslot-ted.a.t approv priate intervals and istitted v with two sets of rollerelements 42 and 43 respectively, the roller elements 42 being arranged.to p05 operatewithsthe inner and outerconcierfaces 3Q and 34, while theother set of roller 125v elements .13 lisadapted to coperatc with the#inner and' outer-cone, rnrfaces 29 and 32..

As thetwmpairs'f eonevsurfaes are rar which are als'oin thisfform o@inventionl 139 3-1 which. is precisely 95 'composite will be; ofcylindrical form with the. axesot one'set arranged at rifrht angles tothe axes of the other set. .In this form of the invention, the two-setsof roller elements are arrangedin tandem sothat` the bearing will-occupya minimum space len thwise of the shaft. -In practice, the adjustablesection 33 of the housing is set'so, that the member 27 may rotatetfreely'u-'ithin thehousing'and without any undue play of the rollerIelements, and -it isadapted for ap plieationl to the shaft when inthiscondit-ion. The construction of. the bearin .is such that it willeffectuall sustain radial stresses an`d also end thrust in either orboth directions.

In that form ofthe invention shown in Fig. 14, the roller elements andcage as shown in the preceding gures may be used. The bearing embodies,lio\ve\er,-a pair of laterally opposed' members 44 and- 45, the member44 having a groove formed in its face to provide' an innercone surface46 and an outer cone. surface 47, while the member 45 is similarlygrooved to form au inner cone surface 48 andan outer 'cone surface' 49,the cone surfaces 46- and 49 being par' allel and adapted to coperatewith the roller elements 48, and the'cone4 surfaces 47 and 48 are alsoparallel and coperate with the other set of roller elements 42. One ofthe'meinbers (the member 45 in the present justably connected to andturnable with the' instance) is secured -withinthe housing or casing 50While the other member 44 is adshaft 51.1 In the`present inst-ance, theshaft 5l is threaded at 52 to receive'a threaded hub53'on the member 44and after the meinher 44 has been suitablyadjusted, a -eotterpin 54 maybe passed throu h the hub 53 and the shaft 'to maintain the adjustment.The housing or casing 50 may also be provided with a flange v55 torotatably receive. the periphery ol the member 44 and, in oi'- der toexclude dust from the bearing, a 4packing ring 56 of .fel`t` or othersuitable material' may be interposed between theparts.
